		Plane of section is parasagittal, demonstrating pars distalis, pars intermedia and pars nervosa with a portion of its stalk.
		Pars distalis can be identified by its large number of chromophobes (pale blue to blue grey), along with occasional acidophils (brownish-red) and basophils (blue to bluish purple); it also exhibits abundant collagenous tissue.
		The pars intermedia (stained a darker blue) is separated from the pars distalis by the intraglandular cleft.

	Example: Neurohypophysis (Site not responding. Last check: 2007-11-03)
		The pars nervosa, which together with its stalk constitutes the neurohypophysis, retains its connection to the site of its origin, the floor of the brain.
		The lumen of the pars nervosa is continuous with the third ventricle, and lined by the same glial element--the ependymal cells--found in the ventricles.
		The pars nervosa doesn't produce hormones of its own, but there are hormones associated with it.

		The pars intermedia is a narrow band of adenohypophyseal tissue that borders the neurohypophysis.
		Pars Tuberalis: This funnel-shaped superior extension of the pars distalis surrounds the infundibular stem (Fig 20-2).
		Pars Intermedia: This is a band or wedge of adenohypophysis between the pars distalis and pars nervosa; it is rudimentary in humans.

		The adenohypophysis consists of the pars distalis, the pars tuberalis and the pars intermedia.
		It lies against the pars nervosa, separated from the pars distalis by colloid-containing vesicles, called Rathke’s cysts, which are the remnants of the cavity of Rathke's pouch.
		The rather grainly appearance of the pars nervosa is due to the abundant pituicyte nuclei.

		The pituitary gland is composed of four anatomical parts: (1) the pars distalis or anterior pituitary; (2) pars tuberalis; (3) pars intermedia, and (4) pars nervosa or posterior pituitary (Pituitary).
		The pars distalis is separated from the pars nervosa by a cleft or row of follicles.
		The pars nervosa or posterior pituitary is composed of the axonal projections of the hypothalamohypophyseal tract.

		The mature adenohypophysis has several distinct parts: the cranial pars distalis, the pars intermedia, which is physically associated with the neural rudiment, and the pars tuberalis, which comes to form a sort of sleeve-like covering of the stalk from which the neural portion is dependent.
		Even though it may be similar to the pars intermedia, the pars tuberalis is quite clearly distinct from the adjacent pars nervosa; it forms a "cuff" or "sleeve" around the stalk of the pars nervosa itself.
		The pars nervosa arises as a ventral outpouching of the floor of the brain, and it retains its connection with the brain.

		The pars nervosa secretes the hormones oxytocin (which causes uterine contractions and milk ejection from mammary glands) and ADH (antidiuretic hormone which causes the kidney tubules to resorb water from the glomerular filtrate and also causes vasoconstriction, hence the alternate name - vasopressin).
		These two hormones, however, are not synthesized in the pars nervosa; they are synthesized by neurons whose cell body is located in the hypothalamus.
		The stimulus for the release of hypothalamic releasing factors (RF) is the circulating level in the blood of the hormones whose output is regulated by the trophic hormones of the pars distalis of the pituitary gland.

	eMedicine - Pars Interarticularis Injury : Article by Gerard A Malanga, MD
		The defect of the pars interarticularis is believed by most authors to represent a fatigue fracture caused by repetitive loading and unloading of this region of the vertebrae from physical activity.
		Green et al concluded from their cadaveric study on pars interarticularis stress investigating mechanical loading that activities involving alternating flexion and extension movements cause large stress reversals in the pars interarticularis, thereby creating the highest risk for developing a pars defect.
		The lateral oblique view, in which the pars interarticularis is best visualized, is described as having the appearance of a “Scotty dog.” In isthmic spondylolytic lesions, the Scotty dog is described as having the appearance of a “collar” or a “broken neck,” which is thought to be a pathognomonic finding (Standaert, 2000).

	Pituitary Gland
		There are three regions of the pituitary gland represented on your slide: the pars distalis (or anterior lobe) and the pars intermedia (or intermediate lobe) of the adenohypophysis and the pars nervosa (or posterior lobe) which is also called the neurohypophysis.
		The intermediate lobe (pars intermedia) is not well defined in the human, and is much larger in animals (i.e., the cat pituitary, Slides 157 and 229).
		The pale staining posterior lobe (pars nervosa or neurohypophysis) is not and does not look like glandular tissue, but appear more fibrous.

		Pars anterior - very cellular; large (acidophils and basophils) and small (chromophobes) in clumps and cords between venous sinusoids.
		Pars intermedia - many small cells (nuclei close together) sometimes form colloid filled follicles, their function in the human is not clear but may be related to corticotrophs.
		Membrane limited granules containing hormone and a carrier protein, neurophysin, are transported down axons (anterograde transport) of hypothalamo-hypophyseal tract to accumulate in axon terminals of pars nervosa.
